    You should see the old FullPaint program, or BillBoard.  Those squares are
    the *only* places where they draw anything.  I have my suspicions they
    made some unauthorised assumptions about what memory was available for
    graphics tinkering -- or even about where the screen actually goes in
    memory.

    How functional everything else was I wouldn't try to say: I had no
    temptation to keep running them when there was a clear possibility they
    were writing over memory they had no business to use.

    However, I would be rather curious to find out exactly what problem causes
    this symptom.

    Would much surprise me, but you can try.
